Announcing Ghost Hunter 1.1 by Subversive Circuits

 At last, a ghost-hunting app for Android that truly lives up to its name. Forget chasing random blobs on a screen, and instead track anomalies through real space.

Imagine the scene: you’re conducting a ghost hunt in a graveyard. Your ghost-hunting app is tracking an anomaly. If you walk towards it, shouldn’t its indicated distance become shorter? If you rotate to face it as you track, shouldn’t the display also change to reflect the new angle? That’s what we thought, and so we sat down to design an app that does its job properly and compellingly.

The result is Ghost Hunter 1.1 by Subversive Circuits. No shock graphics, no fake “radar” readouts. Ghost Hunter 1.1 is designed from the bottom up as a professional piece of software. It uses genuine real time GPS tracking and compass data to create the most compelling “real” experiences for your audiences.

Self-explanatory buttons allow you to display a handy grid, zoom the display, show the distance and direction of a tracked anomaly, and circle it for easy identification.

At just £3.99, it's less than the price of a pint in London. You can download it from Google's Play Store.

The Lodge Spirit Galvanometer

Professor Sir Oliver Lodge was an amazing man. Pipped at the post in demonstrating radio, he was the first person ever to hold the position of Professor of Physics. From the late 1880s, he investigated psychic phenomena in pursuit of new forces that could explain more about nature than electromagnetism and gravity alone. He wrote over 40 popular science books on topics ranging from telepathy to relativity, and was president of the Society for Psychical research form 9101 - 1903. He lost his son, Raymond, in 1915, and wrote widely about his experiences in trying to make contact. One method he used was called a spirit galvanometer.

The sitters would join hands, and the people at the ends of the chain would make contact with a handle each, thereby making a circuit through the coil. Any electromagnetic interaction induces a current in the coil, producing a very weak magnetic field, which moves the compass needle away from its north/south position.

Our version uses advanced artificial intelligence that listens to the room, waits for questions, and delivers the next in a predictable sequence of YES/NO answers. It runs for at least 12 hours on 2 x 20mm coin cells. There are no keyfobs, no receiver, no magnets and no compromise. Punters can even take the galvanometer to another room and use it for real.

Our creepy promo video includes a sequence where I zoom in on the needle while Jo, the photographer on the product shoot, was actually using the device.

We're only making 50 Lodge Spirit Galvanometers at £350 each. Six are already paid for, with inquiries about another four.

We'd like to thank Jo Belfield of Jo Belfield Photography for the excellent photos.
